HYDRO MULTI-B – Pressure boosting made simple

NAMREG - Objective of Multi-B system Fill the gap where Hydro MPC is too large, too complicated and too expensive in markets for constant pressure booster systems. Compliment the current Grundfos Booster Program Differentiate with BoosterpaQ Hydro MPC systems Advance E-solutions benefits to customers Open up sales to other channels Increase overall Grundfos booster system sales Competitively Priced Booster System offering (60-70% of comparable BoosterpaQ system)

Hydro Multi-B - What, Why and How ? SYSTEM OVERVIEW APPLICATIONS SIMPLE TO USE COMPACT SPEED CONTROLLED PUMPS INTEGRATED VFD ENERGY EFFECTIVE ONE SUPPLIER SAFETY FEATURES COMMUNICATION COLLATEROL

Multi-B Pump System – System Overview Simple to use all VFD control pumping system NSF 61/UL372 Drinking Water Approval & UL Listed Packaged Pumping System 2-3 pump systems, CME pumps (I-Version – 304SS) Pump Size: 1.5HP – 7.5HP (CME3 – CME15) Communication capability using CIM cards 36 Catalog P/N systems

Hydro Multi B/E Booster Control Panel Pressure Transducer (Discharge Manifold) Discharge manifold (316 SS) Suction manifold (316SS) CME pumps (I-version 304SS) Oval Flange connection (two per pump)* Pump Isolating Valves (two per pump) Check Valve (one per pump)

Performance Range Q max: 330 gpm H boost max: 231 ft (100 psi boost) Max Working pressure – 232 psi

Applications for Hydro Multi B pump systems Domestic water pressure boosting Pressure boosting in multistory buildings Apartment Buildings Small Hospitals Hotels Large homes Rural areas requiring pressure boosting Anywhere redundant pumping is required

SIMPLE TO USE! Extremely simple HMI! (CU323 controller) Same platform as CU352 controller Automatically ensures best operation in all situations: Number pumps in operation Energy optimized cascade control No need for highly specialized people to operate the system. Less risk for improper use.

Compact! => Easier to retrofit into existing building. => Easier to retrofit existing end suction pumps

Speed controlled Pumps The Multi-B is equipped with speed controlled pumps, which enables the system adapt perfectly to the demand of the system. Operates at a constant pressure Quiet Operation Benefits include: Energy savings. Less wear of pipes due to less risk of water hammer or surges. Smaller diaphragm tank needed High comfort for users due to constant pressure and quite operation.

Integrated VFD – MLE The CME Pump is equipped with integrated VFD/motor combination – MLE The motor and VFD are perfectly matched. Quite operation Some MLE motors use permanent magnet motors 1x230V – up to 2HP 3x460V – up to 3HP MLE motors using permanent magnet motors have combined efficiency (motor + VFD) greater than NEMA Premium Efficient motors alone.

Energy effective The Multi-B has several features that makes it energy efficient. VFD operation ensures that the system delivers exactly what is needed and nothing more. Automatic cascade that makes sure that the optimum number of pumps are running at all time. Special software that ensures low energy consumption during low flow. => Save electricity => Less carbon emission.

One supplier! Grundfos designs, manufactures and assembles all major components of the system. Pumps Motor/VFD System components – Manifolds Controller (CU323) Single Source Responsibility! System undergoes complete system test before leaving the Factory.

Alarms and warnings Dry-running alarm Sensor fault Max. pressure exceed (Setpoint+22 psi) alarm All pumps alarm E-pump alarm Dry running alarm can be set to manual restart, all alarms and warnings can be reset automatically when the actual alarm disappears

=> Protects system against costly breakdowns Safety Features The Multi-B monitors several parameters to ensure that the system is run in a safe way. Water shortage protection (3-5 psi pressure switch standard) Sensor fault protection Max. pressure exceed (Setpoint+22 psi) alarm High voltage, low voltage & loss of phase on input power Monitors if system is outside duty range => Protects system against costly breakdowns

Communication Capable to communicate through the most common BUS protocols using CIM expansion cards. BACnet LON Modbus GRM Can connect into BMS and gives the operator full control of the system. Makes it possible to get alarms remotely, ensuring fast respond to alarms.

Benefits of Grundfos manifolds Reduced pressure drop with smooth transition No stagnant water areas in manifold What are the benefits of the T-drill machining process of the manifold? Key words: No pipe necks Reduced dead water zones (rounded edges) No gaps and cracks reduced hydraulic losses Reduced noise emission Reduced vortex generation when the pumped liquid passes through the manifold
